About the Respiratory System

Human Respiratory System

Did you know that the average person breathes 23,300 times every day? That is about 12-20 breaths every minute! In this article, I am going to explain the fascinating way the respiratory system works.  

What is the respiratory system?

Well, the respiratory system is made up of eight organs: the nose, mouth, pharynx, larynx, trachea, bronchia, lungs, and the diaphragm. Each of these organs has a vital role in allowing humans to breathe. Without taking in fresh oxygen, you would have excessive carbon dioxide and your organs would begin to shut down. You would be dead within about three minutes! 

How do we breathe? 

First air enters through the nose or mouth. The air now travels down the trachea, which is like a straw - movable but somewhat rigid to keep your airway open. The trachea leads to the lungs. After the lungs taken in oxygen the lungs contract, and the carbon dioxide is released from the body in an exhale.

What happens in the lungs?

When we inhale, our lungs take in oxygen from the air. The oxygen is then carried to the bloodstream. The bloodstream delivers the oxygen to all the cells in our body. Cells need oxygen to function. At the same time as fresh oxygen is added, the lungs remove carbon dioxide, a waste product that we exhale. The lungs are made up of a network of airways and tiny air sacs called alveoli, where the exchange of oxygen and carbon dioxide takes place.

How to keep the lungs healthy!

Keeping our lungs healthy is crucial for our health and to make sure we have energy and feel strong enough to do the tasks for each day. There are many ways to help keep our lungs healthy. Five ways to help keep your lungs health are to maintain a healthy diet, drink plenty of fluids, exercise regularly, deep breathing, and maintaining good posture.
  • A balanced diet rich in fruits, vegetables, and whole grains can help support lung health.
  • Drinking plenty of water helps keep your lungs hydrated and functioning properly.
  • Regular exercise can help improve lung function and capacity. Aim for at least 30 minutes of physical activity each day.
  • Deep breathing exercises can help improve lung function and reduce stress. Take a few deep breaths throughout the day to keep your lungs strong.
  • Sitting up straight and maintaining good posture can help improve lung function by allowing your lungs to fully expand.
Another way to keep your lungs healthy is by avoiding things that can harm your lungs. Some things that can harm your lungs include: smoking, pollution, and environmental irritants.
  • Smoking damages your lungs and puts you at higher risk for respiratory diseases. If you smoke, quitting is the best thing you can do for your lung health.
  • Try to limit your exposure to air pollution by staying indoors on high pollution days and using air filters in your home.
  • Avoid exposure to secondhand smoke, chemical fumes, and other respiratory irritants that can harm your lungs.

  What are Respiratory Diseases and Disorders A respiratory disease is anything that impacts the normal function of the lungs. respiratory disease could be as simple as a cold that affects the ease of breathing to severe which might permanently impact how a person's lungs function. Typical lung conditions encompass pneumonia, asthma, lung cancer, and chronic obstructive pulmonary disease (COPD). 10 Deadliest Respiratory Diseases and Disorders Respiratory diseases and disorders can pose a serious threat to life, impacting millions of individuals globally. Here are the 10 deadliest respiratory diseases and disorders you need to be aware of: Chronic Obstructive Pulmonary Disease  - COPD gets worse over time and makes it difficult for a person to breath as it reduces the effectiveness of how the lung functions. In the year 2018, bronchitis afflicted nine million grown-ups.

Medical Advancements in Respiratory Science

  Medical Advancements in Respiratory Science In ancient times, an average of 14% of the population died of respiratory diseases.  Luckily, nowadays there are many ways to help people with breathing problems feel better and improve their quality of life. Oxygen therapy: For those with low oxygen levels, oxygen therapy can help improve breathing and increase energy levels. Respiratory therapy: This regimen comprises physical activity, learning, and assistance aimed at enhancing lung capacity and overall health. Vaccinations: Keeping current on vaccines like the flu shot or pneumonia vaccine can help prevent respiratory infections. Inhalers: Inhalers can help deliver medication directly to the lungs, providing quick relief for symptoms like coughing and wheezing. Airway clearance techniques, such as chest physiotherapy or using a vibrating vest, can help clear mucus from the airways. This can make breathing easier. Making lifestyle changes can help manage respiratory symptoms. These chan
